Ik there are already alot of villian!dekus out there but
If I wrote it (I wish I could write fic) I'd either keep him quirkless or give him a healing quirk.
Quirkless villian
Healing deku here
Imagine how much more terrifying hed be. One of the worlds biggest villians and he uses only his brains. He has no quirk and I'd imagine hed use very little equipment. Nothing more than what youd find in someones home.
At first theyd look for someone with an evasive quirk cause hes so good at getting away. Absolutely no evidence that he was even there beyond the occasional clue just to play with them. Just to prove even with help they couldnt find him. Then theyd look at any powerful quirk and begrudgingly admit hes smart enough to escape the police with ease. They never find out hes quirkless until he let's them and even then everyone doesnt believe it. (I have ideas on how the hero's find that out if anyone wants to know XD)
Knowing hes quirkless doesnt help though. They still have no clue who he is or anything about him except that (and they're not even guaranteed sure). That's still 20% of the population. Theyd have a better chance narrowing it down if he had a strength type quirk or something.
And if they do believe hes quirkless? Then that would mean hes capable of taking down some of the biggest heroes without power. And how do you fight against that? People become very reliant on their quirks cause it's just another tool. But it's easy to take the tool away. Take away their quirk (either permanently, through aizawa or an obvious weakness) and most these heroes have nothing. A quirkless kid?
He already has nothing so unlike the heroes he can adapt to anything.
